The EPL

The EPL is a lab for rapidly prototyping electronics projects. It is meant for students to be able to walk in with an idea and walk out with a fully functioning prototype.

The EPL is on the lower level of the PSU Fourth Avenue Building (FAB) at 1900 SW 4th Avenue in room FAB 84-20. Our phone number is 503-725-2879.

Please consider donating to the lab to help us further our growth. We are a 501c3 and your donation is tax deductible! Email lid@pdx.edu to donate!

Lab Opening!

The EPL is now allowing strictly limited student workspace reservations! Students will be able to reserve a 2 hour slot to work in the EPL. Please keep in mind that if you make an in-person workstation reservation you will be absolutely required to follow all of our safety rules, NO EXCEPTIONS. You will get your temperature taken before entering, masks are required at all times (over the nose), social distancing, and no food or drink is allowed.

The workstation is limited to an isolated work space which includes the following equipment:

Students will also be able to order 3D prints, PCBs, and laser cuts; they can be picked up when a manager is on shift (see our calendar) or during a workstation reservation. Please email epl@pdx.edu for more information.

If you would like to make an EPL reservation please view our Appointment Calendar. You will see 2 hour slots between 12-1600 named ‘EPL Student Workstation Reservation’. The email you use to reserve this slot is the email we will contact for building access, rules, and information, if your reservation does not appear on your calendar please email us at epl@pdx.edu for assistance.

We also have a discord server and slack workspace for students to interact with our managers. You can ask questions about your projects, resources, Analog Discovery 2’s, etc. Join us on discord here and slack here

Online Resources

We understand that many students will still need to do prototyping. Here’s a list of online vendors that will be able to help you complete your projects remotely, besides from the obvious ebay, Newegg, and Amazon.

Site Notes
Circuit Boards  
OSH Park up to 4-layer PCBs, fast turnaround, 1.6 mm and 0.8 mm boards, flex boards
OSH Stencils stainless steel and polyimide stencils
JLCPCB SMT population, lots of board options, stencils
4PCB  
Electronic Components  
Digikey good pricing, normally excellent selection (impacted by COVID-19), excellent part search
Mouser  
3D Parts 3D printing, CNC machining, injection molding, sheet metal, instant quotes from CAD
Rapidmade local to Portland, many other services, instant quotes for 3D prints only
Protolabs high quality, kind of picky
3D Hubs cheap/popular, brokers to small shops, severely delayed shipping due to COVID-19
Xometry good 3D printing, brokered machining
Mechanical Components  
McMaster-Carr large markups, good selection, very easy to find what you need, sells components and tools
MSC Direct decent prices, very good selection, poor interface
Metal Supermarkets metal stock, cut to size, minimal processing available
TAP Plastics plastic stock, cut to size, minimal processing available, also sells tools

Using the Labs

  1. View our Lab Equipment and read the instructions on the equipment you want to use.
  2. Check the calendar for office hours.
  3. Come in during those hours and get trained by a manager on the equipment you want to use.
    • Be sure you’ve signed a liability waiver!
  4. Once you’re trained on a something, you can come in during any office hours and use that equipment.
  5. Pay for parts, materials, and equipment time online.
  6. When you’ve been trained on ALL the equipment you’re eligible to become a manager.
    • This gives you 24 hour card key access, although it does come with a lot of responsibility.
